A bellows that is affixable by way of a connecting sleeve to a machine part, and is made of polymer material and has folds formed, at least in one partial area, in the shape of a screw thread. The connecting sleeve is provided with at least two retaining elements that are distributed in the circumferential direction and project inwardly and/or outwardly from the top surface of the connecting sleeve, the retaining elements being able to be forced into engagement with snap-in locking elements of the machine part, which exhibit a groove following the direction of the folds.
